When used in connection with a radio range bearing. In its first iteration a dme equipped airplane used the equipment to determine and display its distance from. Dmes can also provide groundspeed and time to station readouts by differentiation.

Distance measuring equipment dme in aerial navigation equipment for measuring distance by converting the time a special electronic pulse takes to travel from an aircraft to a ground station and for an answering pulse to return. Distance measuring equipment dme is a system that is used in aviation for navigation purposes.

The received pulses trigger the dme station to reply. Operational notes on distance measuring equipment 1. Signals transmitted between an aircraft and a dme ground beacon enable the aircraft to accurately determine its distance from the beacon.
